Hi!
I will agree with previous comments. Photos are very important, and the banner is the first impression. My banner is not great on this shop that im on but I havent found one I love, love, love yet. My other shop is very hollywood regency, and has worked well. Its bold, modern, black and white...goes okay with what I have but is also being updated.
Your banner, selling vintage items, I think should look a little vintage-y. Something older like this:
http://www.etsy.com/listing/106381923/custom-etsy-banner-and-avatar-design-set?ref=sr_gallery_27&ga_...Idk if you can copy and paste that that showed up, haha but it is clean, and old looking but still classy. Just choose something that is still your style, easy to read, and is easy to the eye. The black looks burlesque, like back then but not classy.
The photos look best on white. If you read other threads everyone stresses white for clean, easy to view, attractive photos.
Even the necklaces if they are on something bright white, they will pop. In this shop, I used a china plate. May not be the best, but for the time being, its better than the couch or something, or a brown table that my other shop items used to be on. Once I changed photos, my sales boooooosted!
To get more traffic match your titles with your descriptions which should then match your keywords.
Your sections are easy, which is nice.
Some of the photography...I was pretty sure it was a photograph but because the image takes up the entire thumbnail and theres no frame, I wasnt toootally sure. Maybe put that in the first part of the title so that its obvious and that will help search words too.
Just my thoughts :).
Btw, I just bought my kids those ironing beads!! They love them. I grew up with them as well. Awesome to see some from back then, haha.
